Location
The power station would be located in the town of Letlhakane, in the Central District of Botswana, approximately 196 kilometres (122 mi) northwest of the city of Serowe, the district capital. This is approximately 500 kilometres (311 mi) northwest of Gaborone, the capital and largest city of Botswana.

Overview
This power station's design calls for use of concentrated solar power (CSP) technology. Under this system of power generation, energy from the sun is trapped by curved mirrors. The light is concentrated to generate heat in the range of 400–500 °C (752–932 °F). That heat is used to boil water to create steam, which is then used to turn electric generators. The design may include the use of molten salts technology to store electricity and release it after sunset and/or before sunrise.
Timeline
The tender documents call for the power station to commence commercial operations in the 2026/2027 financial year (July 2026 to June 2027).
Other considerations
As of September 2022, Botswana's national electricity demand was estimated at 550 MW. At that time national generation capacity was 450 MW. The country imports an additional 150 MW from South Africa. The government of Botswana has plans to increase its installed capacity by developing new solar power stations, thereby achieving energy autonomy from South Africa. This power station is part of those efforts.
